Beautiful rutile quartz bracelet, with attractive transparency and color. - Material: Natural stone (rutile quartz) - Color: Transparent, yellow, black - Style: Bracelet Inner diameter: Approximately 15-16 cm In terms of size, it's a women's size. Since the beads are larger than average, I think men can also wear it if they add their favorite stones to increase the size. 11-12 mm I had it as part of my collection, but I never had a chance to wear it, so I'm selling it. For reference, I bought it for about 30,000 yen at Ishikoro Market. I think the quality is good for the price.
